Not just Exchange. That "no.name.available" and "via smtpd (for [connecting 
ip]) header suggests that the exchange box is frontended with a raptor 
firewall.

I have seen more than one misconfigured raptor frontending an already 
secure mailserver (not just your average insecure exchange / IIS box) turn 
the mailserver it frontends into an open relay.
